{"product_id":"heat-reactive-mug","title":"Heat-Reactive Mug","description":"A cozy, story-driven 11oz color-morphing mug made for early-morning brews and quiet desk moments. When cold, the design sits subtly against a black exterior; pour in a hot drink and a warm illustration comes to life, revealing a friendly, vintage-style “Grunt Grounds” logo and the tagline “Helping those who serve.” The glossy wraparound print keeps colors bright and crisp, while the ceramic body feels pleasantly weighty in your hand. Safe for microwave use and free of lead and BPA, this mug brings a gentle reveal that nudges a smile with every cup. Handwashing is recommended to keep that heat-reactive magic vivid over time.\u003cbr\u003e\u003cbr\u003eProduct features\u003cbr\u003e- Heat-reactive color morphing — image appears when hot liquid is poured\u003cbr\u003e- 11oz ceramic with black exterior and white interior\u003cbr\u003e- Vibrant, full-color glossy wraparound print\u003cbr\u003e- Microwave-safe and made lead- and BPA-free\u003cbr\u003e- Hand wash recommended to preserve heat-sensitive design\u003cbr\u003e\u003cbr\u003eCare instructions\u003cbr\u003e- Hand wash only\u003cbr\u003e","brand":"Printify","offers":[{"title":"11oz","offer_id":45510144983177,"sku":"84556558329111527256","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/8350\/4009\/files\/2278961884993470834_2048.jpg?v=1776053138","url":"https:\/\/gruntgrounds.com\/products\/heat-reactive-mug","provider":"Grunt Grounds","version":"1.0","type":"link"}
